GeForce GTS 250 1GB vs Radeon HD 6670 (OEM) 1GB
Intro
The GeForce GTS 250 1GB comes with a core clock speed of 738 MHz and a GDDR3 memory speed of 1100 MHz. It also makes use of a 256-bit bus, and makes use of a 65/55 nm design. It is comprised of 128 SPUs, 64 TAUs, and 16 Raster Operation Units.Compare those specifications to the Radeon HD 6670 (OEM) 1GB, which uses a 40 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 memory is set to run at a frequency of 1000 MHz on this model. It features 480 SPUs as well as 24 Texture Address Units and 8 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
